ABSTRACT: This study aimed to compare spatial prediction results to map soil textural class names using laboratory results of soil textural properties (sand, silt, and clay) based on USDA soil textural triangle classes' boundary definitions. The study has been done in Dugda district, Oromiya Region, Ethiopia. The study area has been divided into 126 mapping units based on soil-forming factors and soil samples were collected at depths of 0 to 20 cm from each mapping unit. The soil samples were analyzed at the laboratory for textual proportions. These results were used in spatial prediction methods inverse distance weighted, ordinary kriging, and random forest to get continuous raster maps for sand, silt, and clay. The raster maps were used as input layers to develop the twelve soil textural.....

ABSTRACT: Background: Sesame is one of the most ancient oilseed crops, adapted and grown in almost all tropical and sub-tropical regions of Africa. The presence of some antioxidants (sesamum, sesamolin and sesamol) makes the oil one of the most stable vegetable oils in the world. However, due to poor quality it can only be used for industrial purposes resulting in a far lower price than food grade sesame. The poor-quality sesame, exacerbated by poor production practices, is characterized by high incidences of aflatoxin produced by Aspergillus species. Therefore, there is the need to investigate the effect of seeding rate on the vegetative growth, yield and grain quality of two sesame varieties planted early season.....

ABSTRACT: The Air-suction seeder is widely used in the field of precision seeding in China. Air-suction metering device is the core component of the air-suction precision seeder, and its performance has a significant impact on the quality of sowing. By introducing the research status of domestic air-suction metering devices, the related factors and research methods affecting the performance of air-suction seed metering devices were elaborated on in detail, which provided the reference for the design and performance research of domestic air-suction metering devices..

ABSTRACT: The study was conducted to evaluate the nutritional composition of okra waste, growth performance, carcass yield, organ weights and cost benefits of finisher broiler chickens fed dietary levels of okra waste .one hundred and forty four pieces of unsexed four weeks old Ross 308 broiler chickens with the average weight of 0.85kg were used for the study that lasted for four weeks. Significant (P<0.05) differences among treatment groups in weight gain, average daily feed intake, feed conversion ratio, mortality, organ such as the liver, gizzard, heart,carcass weights and cost analysis were observed. The study suggests that supplementing broiler diets with up to 10% okra waste isideal in feeding finisher broiler as it brings about a drastic reduction in the feeding cost without compromising the performance, organ and carcass weight of the experimental birds.

ABSTRACT: Background: Cowpea seeds are susceptible to seed deterioration during storage. Therefore, a treatment is needed to improve the viability of the seeds, including in the form of seed invigoration by seed priming. The purpose of this study was to study the effect of the type of water hyacinth root extract on the viability of cowpea nagara seeds and determine the best concentration for its effect on viability of nagara cowpea seeds. Materials and Methods: The experiment was carried out in April - November 2022 at the Plant Physiology Laboratory, Faculty of Agriculture, ULM Banjarbaru which arranged in a Nested Design repeated 3 times. Five levels of concentrations nested.....
